Ok the computer is really starting to take shape. So, the schematics for the ALU ARE DONE!!! and will upload them in a pdf. The accumulator is also done but the main processor...well....lets just say i needs to be checked first.

If someone could check it for me the just send me a message by this forum or :

the code is as follows:

0000 - add (adds two numbers and stores in accumulator)
0001 - adm (adds number...

I have completly redesigned the ALU after discovering i need decoupling capacators and open collectors. I am using the Eagle software to draw the schematics and convert to PCB, man....I have never used such a brilliant program for auto-routing. This thing can route ANYTHING!!!

Well I have finished the ALU design and just need to implement this to a PCB. Instead of the traditional "everything on one board" I have designed mini boards that fit in a mini shelf (i mean really small). This way its easier to find a problem and fix.
